Embodiment Construction
[0057] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0058] combine Figure 1-2 , the structure and working principle of the cube star brake sail burning wire mechanism of the present invention are as follows:
[0059] The brake sail burning mechanism includes a mounting panel 2, a strong horse wire 7, a pressure rod 8, a rotating shaft 12, an extension spring 14, and a separation switch 23. One end of the depression bar 8 is rotationally connected with the rotating shaft 12, and the rotating shaft 12 is fixed on the mounting panel 2 by screws, and the other end is fixedly connected with an end of the tension spring 14, and the other end of the tension spring 14 is fixed on the mounting panel 2, and the tension spring 14 Not on the same straight line with depression bar 8. During the compression state, the depression bars 8 of the two sub-mechanisms are parallel to each other, and the disconn...

The invention discloses a power supply and control circuit applied to a cubestar brake sail, including a power supply circuit and a control circuit. The front end of the power supply circuit is connected to a solar battery array provided solely by the cubestar for the brake sail device, and is charged through a supercapacitor therein. After the circuit is converted, it is converted to the bus voltage and charged to the supercapacitor module. The bus voltage is converted to 3.3V voltage after passing through the 3.3V converter, which supplies power for the chips in the burning circuit and the control circuit. The burning circuit is in the control circuit. Under the control of the circuit, use the busbar to blow off the Dalima line that is tied to the fixing device, release the braking sail, and feed back the unfolding state of the braking sail to the control circuit; The station reports the status of the brake sail. The power supply and control circuit of the present invention can work independently of the satellite platform, and even if the satellite fails, the braking sail can be deployed at a preset deployment time to speed up the de-orbiting process of the satellite.
Description
technical field [0001] The invention relates to the field of spacecraft off-orbit control, in particular to a power supply and control circuit applied to cube star brake sails. Background technique [0002] In recent years, with the rapid development of communication, optoelectronic components, materials, sensors, and other technologies, cube satellites with low cost and high functional density have gradually emerged, which greatly reduces the development cost and development cycle of satellites. Remote measurement and testing have gradually become a trend. [0003] In recent years, countries have launched more and more cubesats, most of which do not have their own deorbiting systems, and the design life of cubesats is generally only 1-3 years, while slow deorbiting in the natural state takes at least 10 years , leading to an increasing amount of space junk in Earth orbit, which becomes a potential danger to effective orbiting spacecraft, and is not conducive to future huma...
